Coarticulated pulmonic consonants

ʍ	Voiceless labial-velar fricative (approximant)
w	Labial-velar approximant (semivowel)
ɥ	Labial-palatal approximant (semivowel)
ɕ ʑ	Alveolo-palatal fricatives
ɺ	Alveolar lateral flap
ɧ	Supposedly, simultaneous ʃ and x. In practice, mostly used for a macrophoneme of Swedish varying from [fʷ] to [ʂ] to [χ].
Affricates and double articulations can be represented by two symbols joined by a tie bar if necessary. k͡p t͡s

Non-pulmonic Consonants

Clicks	Voiced Implosives	Ejectives
ʘ Bilabial	ɓ Bilabial	ʼ as in:
ǀ Dental	ɗ Dental/alveolar	pʼ Bilabial
ǃ (Post)alveolar	ʄ Palatal	tʼ Dental/alveolar
ǂ Palatoalveolar	ɠ Velar	kʼ Velar
ǁ Lateral alveolar	ʛ Uvular	sʼ Alveolar fricative

Unicode symbols for voiceless implosives exist (ƥ ƭ ƈ ƙ ʠ) but these are considered depreciated.
